The pathological diagnosis report of cancer is usually issued in a week or ten days, but the specific situation should be analyzed, and there are usually the following possibilities: 1. If the clinical specimen is a biopsy specimen, the tissue volume is not large, and the number of specimens taken is relatively small, so the process of pathological section preparation is relatively simple and fast, and the pathological changes of the lesion are typical under the microscope. In this case, the pathologist’s diagnosis is relatively simple and easy, and the pathology report can be issued soon; 2. If the clinical specimen is a large surgical specimen, such as a whole organ, multiple lesions, or tissue with lymph node dissection, in this case, the number of pathology sections will be larger, and the tissue will go through a series of pathological production process, which is complicated, and the number of paraffin sections is larger, and some cases can reach dozens of sections. Some cases can reach dozens of sections, so the pathologist must carefully observe each section under the microscope, comprehensive analysis, and finally be able to complete the final pathological diagnosis report; 3, if the specimen sent for examination is difficult, rare, or complex cases, if necessary, immunohistochemical staining or genetic testing analysis, combined with the above staining comprehensive analysis, which takes a relatively long time.
